Public data to be released to handful of scientists and institutions for research

We don't know if we are fascinated by this or not when Twitter is releasing the public data to the handful of scientists and institutions for research projects. What if the data is sent to the bad scientists? Will there may be some sort of evil revenge taken by those scientists? Also, we don't know if this is going to be a bad move or not? The positive side about this movie is that in case someone is suffering from some disease and he has already tweeted things about that, at least, people related to him can know his tweets. However, for the institutions, there are already some schools with bad policies that invade the students' privacy and this can be a serious problem. First, the negative tweets targeting someone or something in schools are likely to be one of the problems but then, such standard educational abuses can be easily investigated by Twitter.
